Living with Miller syndrome

A rare condition that mainly affects how the face, arms, and legs develop, including small jaw, cleft palate, and missing pinky fingers and toes.

Understanding Miller syndrome

Miller syndrome is a rare condition that mainly affects the development of the face, arms, and legs.

It varies from person to person. Facial differences can include underdeveloped cheekbones, a small lower jaw, and a cleft palate with or without a cleft lip. These can cause feeding and breathing problems in infants. Many people have small, cup-shaped ears and hearing loss from middle ear differences. The most common limb difference is missing fifth (pinky) fingers and toes. Extra nipples and heart differences have also been reported.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Small lower jaw (micrognathia)
  • Cleft palate, with or without cleft lip
  • Missing pinky fingers and toes, or fused fingers and toes
  • Underdeveloped forearm bones
  • Small, cup-shaped ears
  • Hearing loss from middle ear differences

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists, ear, nose, and throat specialists, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in DHODH are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    World Craniofacial Foundation may keep lists of experts for this condition.

Bring these questions to your next doctor visit
Can genetic testing for the DHODH gene confirm this diagnosis?
What feeding and breathing supports does my child need?
Should we have hearing tests, and what care is there for the hands and feet?
